Allium caesium shines in the early summer garden, displaying sky-blue florets that form 2-to-4-inch globe-shaped flower heads. Individual flowers are accented with indigo striping. Allium caesium is an heirloom variety considered to be the best blue allium available. Fragrant blooms last long in the garden and in cut flower bouquets. Bulbs multiply each year, forming a nice flower cluster.

Description

Growing Alliums: The Allium family includes onions, leeks, and chives, but the ornamental varieties have become increasingly popular with gardeners thanks to their unique beauty. Globe-shaped flower clusters float above thin, elegant flower stalks. Allium bulbs are planted in fall, and bloom in late spring, bridging the gap nicely between spring-blooming flower bulbs and early summer perennials, such as Peonies, Poppies, and Salvia. For a pop of color and texture, plant Alliums in groups, or plant among perennials. Within their hardiness zones, they will return year after year and may naturalize and spread over time. Leave spent flowers standing to add interesting texture to your garden through the fall and winter.
